TechMatte's Air Vent Car Mount is one of the most popular smartphone mounts on the market right now, with an average rating of 4.5 stars out of 5 over on Amazon. It's also usually fairly cheap, coming in at $7.99 normally. However right now you can get it for just $3.99 (with promo codeCBBN7MDI), cutting that normal price in half, essentially. Which is pretty impressive, and it's a deal that many people are going to have a tough time passing up, especially if they are looking for a car mount for their smartphone.
This car mount attaches to the air vent in your car (as you can tell by the name of the product), and then it uses magnets to hold your smartphone in place. Simply attach the magnet to your smartphone and then just slap it on the mount and you're good to go. Now if you don't want to put a magnet on the back of your phone, you can also attach it to the inside of the case on your phone. This way you won't damage your smartphone when you want to remove the magnet to sell it or something similar. It's a great way to still use your phone for navigation and for music in the car, without being distracted by your phone while you're driving.
